[mpich-discuss] unable to start mpd on Scyld Beowulf Cluster compute nodes

[Rajeev Thakur]

May be something with the networking configuration on the machines. To
debug, you can use the mpdcheck utility and follow all the steps described
in the installation guide.

Subject: [mpich-discuss] unable to start mpd on Scyld Beowulf Cluster
compute nodes


Hello,
 
My system is an AMD Opteron cluster running Penguin Computing Scyld Linux
release 30cz, with a full linux on master node but thin kernel on compute
nodes. Communication mostly thru bproc. rshd is also enabled on compute
nodes for a separate mpich1. 
 
After installation of MPICH2, no problem starting mpd on master node. But
launching mpd always exit silently, using bpsh, or rsh to compute node then
start it. PYTHONHOME has set properly to import the required libs. Files
resident on master node are recognized by same path in compute nodes via
NFS.  Clueless what else needed for such a system to bring up mpd. 
 
Any advices are appreciated. Thank you in advance.
